[Dovecot] Upgrading from Package on OpenBSD

[Michael Starks]

Hi,

First, let me say I looked for a way to search the archives online but 
must be missing something.  Can someone point me to a URL?

On to the question:  I'm currently running dovecot-0.99.14p1 from 
packages on OpenBSD 3.8.  I'm interested in running the latest version. 
  What is the best practice for migrating/upgrading on OpenBSD?  Thanks 
in advance.
